An adaptor (26) for enabling small electrical cells (30) to be charged in a charger (10) designed to mate with and charge large cells. The adaptor has a recess for holding a small cell, is shaped and sized similar to the large cell, and has conductive parts (42, 44, 50, 54, and 52) designed to conne
An adaptor (26) for enabling small electrical cells (30) to be charged in a charger (10) designed to mate with and charge large cells. The adaptor has a recess for holding a small cell, is shaped and sized similar to the large cell, and has conductive parts (42, 44, 50, 54, and 52) designed to connect the contacts of the small cell to the terminals (22, 24) of the charger when the adpator is positioned in the charger. The adaptor is cylindrical, has an insulating body portion (36) and conductive, removable top and bottom caps (44 and 42). A hole or channel (48) through the body portion contains a spring (50) and a space to receive the small cell.

For use with a charger having a pair of relatively widely-spaced terminals for mating with and charging an energy storage cell having a pair of correspondingly widely-spaced contacts, an adaptor for enabling an energy storage cell having a pair of relatively closely-spaced contacts to be charged in
For use with a charger having a pair of relatively widely-spaced terminals for mating with and charging an energy storage cell having a pair of correspondingly widely-spaced contacts, an adaptor for enabling an energy storage cell having a pair of relatively closely-spaced contacts to be charged in said charger, said adaptor comprising: means for (a) holding said energy storage cell having said closely-spaced contacts, (b) causing said relatively-closely spaced contacts of said cell, when said cell is held in said adaptor, to be connected electrically with said respective pair of terminals of said charger, and (c) enabling said adaptor to mate physically with said pair of terminals of said charger, said adaptor having a substantially cylindrical shape, said adaptor comprising a body portion and removable mating top and bottom portions, said body portion having an axial through hole extending through said body portion from the top to the bottom thereof, a spring positioned in said axial through hole and, when relaxed, occupying substantially the entire length of said through hole in said body portion, said removable top and body portions each comprising a cap which covers a respective end of said through hole so as to captivate said spring, said caps each providing an electrically conductive path from said spring, when said spring is in contact with an interior side of said cap, to an exterior portion of said cap, each cap mating with said body portion in telescoping relationship and being partially extensible from said body portion in an axial direction without freeing said spring, whereby energy storage cells of a wide range of lengths, and hence contact spacings, can be held in said adaptor, and a cell of very short length easily can be positioned in the top of said through hole of said adaptor by partially withdrawing the bottom cap from said adaptor to allow said spring to drop down to provide a recess at the top of said through hole, placing said short cell in said recess, fully assembling said top cap to said adaptor, and then fully assembling said bottom cap onto said adaptor to compress said spring.
